Let me know, and I'll PM it to you
Yeah it's worth a shot. Do you have your original file as well? This suggests you managed to edit it fine, and it still worked...
We have tried switching the flag for locked to 0x00, from 0x01, but it didn't work. Would be interesting to see the file though after using a code, to see if the flag is now at 0x00
Really what we might need is a BEFORE and AFTER from an unlock.
ie. anyone getting a code, could you get a dump of this file BEFORE the unlock, then enter the code, and then RE-dump to another file. Call them before and after perhaps? Then we can see what actually happened after the unlock - perhaps a checksum gets re-calculated, or a second "backup" bit was flipped that we missed?
My email, for anyone wanting to send their file (it's only 2 MB so goes fine as an attachment) is (the lines stop OCR gathering it for spam =D)
